DOI: 10.1007/s40571-020-00335-4
Abstract: When a dynamic earthquake rupture propagates on a fault in the Earth’s crust, the medium around the fault is dynamically damaged due to stress concentrations around the rupture tip. Recent field observations, laboratory experiments and… read more here.

DOI: 10.1190/int-2020-0017.1
Abstract: Faulting processes have created large damage zones with complex structures in the field; however, estimating the width and geometry of such fault structures in the subsurface is challenging due to a lack of data. Seismic… read more here.
